DRIVING MECHANISM FOR PAPER-REFINING ENGINES.

Specification of Letters Patent.

To all whom it may concern:

Be it known that we, SOLOMON R. WAGG and WILLIAM L. WAGG, citizens of the United States, residing at Appleton, in the county of Outagamie and State of VVisconsin, have invented new and useful Improvements in Driving Mechanism of Paper-Refining Engines, of which the following is a specification.

This invention relates to improvements in the driving mechanism of paper refining engines and particularly to paper refining engines of the Jordan type which, as is well known, comprises a stationary frusto-conical shell within which is mounted an endwise adjustable plug, the shell and the plug being provided with co-acting cutting knives which, as the plug' rotates, comminute or grind up the material in the shell. Up to a comparatively recent period refining engines of the type stated were always belt driven. The disadvantages of the belt drive induced a motor driven design in which the motor shaft was positioned in alinement with the shaft of the plug. A preferred form of this design and which experience has demonstrated to be of greater advantage, proposes a rigid coupling between the shafts of the plug and of the motor. In the original conception of the design a slidable coupling was proposed but experience soon demonstrated that, with this arrangement, the lateral sag of the plug caused a binding in the shaft coupling which affected the alinement of the parts, prevented the eflicient transmission of power, and interfered with the ready operation of the adjusting mechanism. The naked fact of the rigid coupling between the shafts of the plug and of the motor whereby these parts may be moved endwise as one, has not, of itself, been suflicient to wholly overcome the objection referred to, since there are considerations which this arrangement fails to regard. One of these considerations is that the great weight of the motor puts an undue stress on the shafts and on the coupling, during the endwise or axial adjustment of the cone, and the effect of this stress is to interfere with the proper alinement of the motor parts, to produce loose play of the coupling and to injuriously affect the bearings.

The present invention proposes to overcome these objections by taking from the shafts and the couplings all the stresses heretofore incident to the pull or drag of the motor during the endwise adjustment of the cone and by so distributing these stresses that they have no injurious effects. Toward the accomplishment of this object the invention proposes the rigid connection of the motor to a tail boX or equivalent part of the machine which is moved with the shaft and by an adjusting screw. The connections provided for this purpose comprise a cross bar which is attached to the tail box or equivalent part and tie bars which connect the cross bar and the motor casing, and which may be of any desired number and material. r

A further object of the invention is to improve the construction of the motor base, to provide for an easier running of the movable parts.

An embodiment of the invention is illustrated in the accompanying drawings, wherem Figure 1 is a plan view illustrating the application of the present improvements to a motor driven Jordan engine; and Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1.

Similar characters of reference designate corresponding parts throughout the several views.

The engine proper includes the usual frusto-conical shell, as 1, supported by brackets, as 2, from a base, as 3, and containing the usual conical plug (shown in dotted lines) which is mounted upon and driven by a shaft, as 4, projecting from each end of the shell 1. At the end of the base 3 opposite to the shell 1, an electric motor, as 5, is mounted and its-shaft, as 6, is coupled to the shaft t by an approved coupling, as 7, which preferably includes an alining pin, as 7 ,-fitted dowel-fashion in recesses formed axially in the adjacent ends of the shafts 4 and 6. Said shafts being thus coupled by the device 7 form in effect one continuous shaft, common to the plug and to the motor. In environments where electric power cannot be obtained, the driving of the plug may be efi'ected by a belt transmission and for this purpose the shaft 4 may be provided with belt pulleys, as 8. These are of split construction in order that their assemblage and removal may be effected without interference with the rest of the organization.

The bearings, as 9, in which the shafts 4 and 6 are journaled, are of improved construction, although they form no part of the present subject matter of invention. They will, therefore, be only briefly referred to. Said bearings are each of two-part construction, the parts being connected by bolts, and being associated with the shafts for endwise movement therewith, in order that their proper relation may always be preserved without regard to the relative positions of the plug and the shell.

The bearing 9 at the front end of the machine is associated with or forms a part of the tail box 10 and is connected by a swivel joint, as 11, to the threaded staff of the usual hand wheel adjusting device 12. To this tail box bearing is rigidly secured a cross bar, as 13, which is of greater extent than the greatest diameter of the cone, in order that its ends may project beyond the sides of the cone. The cross bar 13 is rigidly connected to the casing of the motor 5, as by longitudinally disposed tie bars 14. Each tie bar 14 has its ends threaded, one of the threaded ends being passed through the adjacent end of the cross bar 13 and held in proper relation thereto by lock nuts, as 15, and the other threaded end being passed through a clip or socket, as 16, rigidly secured to the motor casing and held in proper relation to said clip or socket by lock nuts, as 17. The tie bars let are practically coextensive with the shafts 4t and 6 in their connected relation and it follows that the stresses incident to the pull or drag of the motor are taken up by these tie bars. Therefore, such stresses will not have an injurious effect upon the alinement 0f the motor parts, upon the coupling and upon the bearings. Since the cross bar 13 is rigidly secured to a movable part of the tail box, the improvements herein described, are as readily applicable to old machines in service as they are to new machines at the factory. The tie bars are symmetrically arranged with re spect' to the other parts of the machine in order that the distribution of stresses may be uniform and may be used to any desired number. They may also be of any desired material, 6. 9. metal or wood.

The invention also includes an improvement in the motor mounting or base construction. By reference to Fig. 1, it will be noted that the bearings, in which the motor .ened side portions of the plate 19 and in which are fitted roller bearings, as 23, upon which the plate 19 rests. To maintain the plate 19 in proper relation with the base 21, hangers, as 24, are provided at the sides of said base, each hanger carrying a roller, as

25, which engages the upper face of the plate 19. The rollers 25 serve primarily as retaining devices for the plate 19 and incidentally have a tractive engagement with the upper face of said plate in order that its movements may be rendered more easy.
